Title: Jet propulsion units
Inventor: PARIS FRANCOIS GILBERT
IPC: F02K7/20
Filed: 1951-04-16
Abstract: 715,323. Jet propulsion plant. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. April 16, 1951 [Oct. 7, 1950], No. 8839/51. Class 110(3) A jet propulsion unit comprises a ram jet duct having in succession a frontal air intake of diverging form, an intermediate portion of greater cross section and a rearwardly directed propulsion nozzle and a pulse-jet unit substantially entirely enclosed by air flow in the ram jet duct having inlet adjacent or near to the intermediate portion of the ram jet chest and its combustion chamber at least partly inside the intermediate portion. A pulse-jet unit is defined as a pulsatory combustion chamber and a nozzle which ejects the gases intermittently. In the arrangement shown Figs. 1 and 2, four pulse jet units p<SP>1</SP>, p<SP>2</SP>, p<SP>3</SP> and p<SP>4</SP> are arranged in the casing, 1 forming a ram jet unit. Air entering the casing 1 at 2 is slowed down in a diffuser 5 and then divided. Part of the air enters the inlets 4 of the pulse jets and part flows over the pulse jets to the propulsion nozzle 3. The air passing through the inlets 4, which are provided with aerodynamic valves, enters pulsatory combustion chambers 6 which exhaust through tubes 7. The tubes 7 are surrounded by nozzle 8 which allow part of the air which has passed over the pulse jets to mix with the combustion gases from these jets. An aerodynamic valve is a valve which has a greater resistance flow in one direction than in another. These valves allow a certain amount of the combustion gases to flow back through the inlets 4 and to avoid the loss of these gases a bent tube 13 is provided to lead them in the same direction as the flow through the ram jet. The combustion chambers of the pulse jet units may be provided with fins 11 so as to assist in the transfer of heat to the air passing over the units. Some of these fins may be extended as at 12 to enable the pulse jet units to be supported relative to one another and to the casing 1. In a modification, the pulse-jet units are arranged in line and are surrounded by a ram jet of elongated form. This unit is stated to be suitable for installation in an aircraft wing with its inlet situated near the leading edge and its outlet near the trailing edge of the wing. It is also stated that supplementary fuel may be burnt in the ram jet unit. The outlets 10 of the pulse-jet units may be arranged, as shown after the outlet 3 of the ram jet or may terminate a little before the outlet 3. Additional fuel may be burnt in the airflow through the ram jet duct. Specifications 653,629 and 711,281 are referred to.

Title: Improvements in friction clutches and brakes
IPC: F16D43/18
Filed: 1922-03-28
Abstract: 199,796. Lancashire Dynamo & Motor Co., Ltd., and Whitmore, H. B. March 28, 1922. Clutches, friction of the type in which adjustably-weighted segmental shoes driven from their trailing ends by projections of the driving-element are adapted to expand centrifugally into engagement with the cylindrical inner surface of the driven or stationary element. The driving- projections, in the form of pins or lugs, are furnished with leather or other flexible and renewable thrust-transmitting pads or washers. The driving-projections are preferably arranged between the shoes, so that drive may be in either direction, and the ends of the shoes may be so shaped that the thrust thereon augments, opposes, or has no effect on the engaging-force. In the clutch shown in Figs. 1 and 2, a drum B, forming with an integral or attached extension B<1> a belt pulley, runs freely on a bush A keyed to the end of a driving-shaft (not shown). The bush A has a flange a<1> carrying pins a<3>, on which are threaded a number of approximately rectangular leather washers D held in place by nuts a<5> and a ring E. The washers D contact with the end faces c<1> of shoes C, which are provided with adjustable weights c<3> threaded on screwed stems c<4>, and have riveted to them woven asbestos fabric or other 'friction facings c<2>. A plate F encloses the clutch parts, and through this plate passes the stem of a grease lubricator g<1>. The lubricator is screwed into a plate G, which is secured to the bush A and encloses a cavity between itself and the shaft end. Grease passes from this cavity by grooves in the shaft or bush to an annular chamber a<6>, and thence by passages a' to the boss b<1> of the pulley. In a modification, Figs. 6 and 7, the driving-member has radial arms a<9> having projecting lugs a<8>, to which are riveted U-shaped leather pads D<1>. The cover plate, ring E, and lubricator g<1> are disposed as shown in Figs. 1 and 2. The shoes C may be castings or, as shown, may be bent up from bar metal; their ends c<1> may be parallel or inwardly convergent or divergent, and the lugs a<8> may be conformably shaped; a ridge may be formed across each face c<1> in order to localize the driving-thrust. In a further modification of the construction shown in Figs. 6 and 7, the pads D<1> are replaced by discs, each held in a recess in the faces of the lugs a<8>, and built up of cylindrical washers or of a spirally-wound leather strip. In any of the forms, the driven element may be keyed to an aligned shaft, and is then in the form of a drum overhanging the driving-shaft and provided with a cover plate apertured to run on the driving-bush A. Where springs are used to prevent engagement below a predetermined speed, they may take the form of blade springs H, Fig. 20, acting on the stems c' and bearing under lugs a<8>. In modifications, the stems are similarly connected to a deformable spring ring or to helical tension springs.

Title: Improvements in reciprocating mechanisms
IPC: F23K3/00
Filed: 1926-04-07
Abstract: 274,165. Phillips, W. H. April 7, 1926. Fuel, feeding.-A reciprocating mechanism, more particularly adapted for swinging one or more spouts 61, Fig. 1, feeding fuel to a hopper 60 of an automatic stoker B of a furnace A, comprises an assembly attachable as a unit to the furnace front and having one or more devices adapted for readily engaging and disengaging the lower ends of the spouts so that, when desired, the spouts may be operated manually by means of a handle 63. A channel-shaped casing 2 secured to the front of the furnace carries an endless chain 10, Fig. 7, entrained over a sprocket provided with a drive connected with the drive of the stoker B, and over a second sprocket which may be adjustable in a trackway 3 to keep the chain taut. The engaging mechanism comprises a housing 25 provided with vertical side lugs 26 carrying rollers 27 for movement along the trackway, and with a sprocket 28 reinforced at both sides by discs 41 and mounted around a collar 30 on a bolt 29. The bolt 29 also secures in position a cover-plate 31, Fig. 6, provided with lugs 32 fitted with pins 34 pivotally carrying a spout-engaging yoke 33. The yoke may be swung upwardly so as to disengage it from the spout, whilst the pins 34 may be withdrawn so as to remove the yoke altogether. The sprocket 28 is provided with teeth 45, preferably in pairs, for engaging the chain 10, and with openings 40 adapted alternately to register with internally threaded bosses 39 formed integrally with a bar 38 secured to the rear of the housing 25. Mounted in the bosses 39 are a pair of pins 48, 49 having shanks 50, 51, one righthand and the other left hand threaded, the pins having reduced ends 52 which engage one at a time with one of the openings 40. The outer ends of the pins 48, 49 are secured to fingers 53, 54, connected by a spring 55, and adapted to engage rollers 58, Fig. 5, or other tripping members provided on brackets 56 secured, preferably adjustably, at each end of the casing 2. By this means, when the housing approaches say the left hand end of the casing the finger 53 engages the roller 58, thereby rotating shank 50 of pin 48, and withdraws its reduced end 52 from one of the openings 40. The sprocket 28 then rotates slightly so that one set of teeth 45 is disengaged from the upper run of the chain 10 and another set engages the lower run. At the same time another opening 40 is brought into alignment with the reduced end 52 of pin 49 and by means of the spring 55 the shank 51 is rotated to lower its reduced end 52 into the aligned opening 40. The sprocket 28 is then again prevented from rotating and the housing is caused to travel to the right. The Specification describes and illustrates the arrangement of two or more spouts so as to obtain a " balanced drive."

Title: Improvements relating to the production of sponge metal
IPC: C21B13/08
Filed: 1949-04-06
Abstract: 674,236. Manufacture of iron; extracting metals. STORA KOPPERBERGS BERGSLAGS AKTIEBOLAG, KALLING, B. M. S., and DRAGGE, O. J. L. April 6, 1949, No. 9386/49. Classes 72 and 82(i) [Also in Group XII] A method of producing sponge metal, e.g. iron, comprises charging metal oxide ore and reducing agent, in excess of that required for the reduction of the ore and the generation of heat by combustion, in fine granular form into a substantially horizontal rotary furnace, continuously rotating the furnace to cause a tumbling action within the charge and provide a sloping upper surface substantially of reducing agent, and generating the heat for the reduction of the ore by continuously blowing gas containing free oxygen against the surface of the charge simultaneously to burn solid particles of the reducing agent and combustible gases evolving from the charge. The reducing agent may be charcoal or coal or coke, in which case lime or other material for combining with the sulphur is added, and the ore is crushed, or sintered and briquetted with sulphite lye, to a particle size greater than that of the reducing agent. The charge preferably occupies not less than 25 per cent of the furnace volume. In one type of apparatus for carrying out the above process, Fig. 1, the ore and reducing agent are fed from a hopper 18 into a rotary furnace 10 and oxygen containing gases blown in through a pipe 19. The reduced sponge is sieved from the excess reducing agent by perforated plates 21 which rotate with the furnace body and discharge the sponge through a sluice device 23, fitted to prevent escape of the gaseous combustion products. In another form the gases are fed in through the discharge end and the excess reducing agent, sieved from the sponge metal, blown in with them. The finest particles of the reducing agent in both cases may be introduced in an intermediate zone of the furnace. The discharged sponge may be passed through a heat exchanger to preheat the gases or the charge.
Patent GB-493355-A (GB)
Title: Improvements relating to magnetically operated electric switches
IPC: H01H51/28
Filed: 1937-04-02
Abstract: 493,355. Mercury switches; magnetic .switches. CIANCHI, A. April 2, 1937, No.9464. [Class 38 (v)] In a mercury or other sealed-container switch having electrodes 2, 3 sealed into the container 1 and an armature 6 which moves so as to cause the electrodes to be electrically connected or disconnected, one of the electrodes 3 is made of magnetic material and is magnetized by a separate solenoid or magnet 12 arranged outside the container. In the form shown in Fig. 1, alternating current from a source 9 energizes a winding 8 which pulls the armature (i on a float 5 into the position shown in which mercury passing through a hole 7 connects the electrodes 2, 3. In this position, the magnetized electrode 3 attracts a second armature 11 on the float and prevents chattering. The above switch could also be operated by direct current, the magnetized electrode 3 in this case serving to hold down the float after the circuit to the winding 8 is broken. The float could then be released to ''open" the switch by moving the magnet 12 away, either by hand, Fig. 2 (not shown), or electromagnetically, Fig. 3 (not shown). In another modification, Fig. 4, a winding 16, tending to demagnetize the electrode 3, is arranged in series with the electrodes 2, 3. Normally the effect is insufficient to release the float 5 but excess current does this and so opens the circuit. In a modification of this form, the magnet 12 is dispensed with and the winding 16 serves to magnetize the electrode 3. Release is then effected by failure of current. In other forms, Figs. 5 and 6 (not shown), adapted for direct and alternating current respectively, movement of a single switch arms causes the successive energizations of the windings 8, 16, and in still further forms, Figs. 7 and 8 (not shown), movement of an electricallyheated bimetallic strip actuates the float either by energizing the winding 8 or by bringing a horse shoe magnet up close to the outside of the container. The movement of the float besides closing the circuit 2, 3 short circuits the heating winding of the bimetallic strip so that this moves back but the float is held by the magnetized electrode 3 as before. Specifications 481,289 and 485,259 are referred to.
